Smokey exhaust, oily plug, when covering/blocking exhaust at tickover dosen't cut out (JL exhaust badly leaking anyhow) rev's didn't increase when draining gearbox oil but oil was frothy and light green in colour

Not noticably, I usually put in 500ml. I drained it out into a seperate tub. When I get chance I will put this into old g/box oil bottle and see if if any has been lostbristolmod wrote:generally if the D/S seal has gone, the smoke will be white and smell bleedin' awful.
Is the crankcase oil level dropping?
